The object of the present invention is to provide an adjustable device for unbalanced windows which can be used for manually lifting the lower sash o the window and can be operated at the same t me to support the window in various adju-ted onen positions.

A further object of the invent on is to construct the device from pressed sheet metal for cheapness and sim licity of manufacture.

A further object of the invention is to design the device for screw attachment to the sash, and such, that the screw heads will be invisible when in o eration.

A st ll further object of the invention is to provide means for adjustment to accommodate wear.

With the above important objects in view, which will become more apparent as the description proceeds, the invention consists essentially in the construction and arrangement of parts hereinafter more particularly descr bed. references being had to the accompanying drawings in which:

Figure 1 is a perspective view of the lower part of a window showing the devices attached, in operable position, on either side of the sash.

Figure 2 is a face view of the lifter and holder as used on the left s de of a sash.

Fi ure 3 is a vertical sectional view taken on the line 3--3, Figure 2.

Fi ure 4 is a reverse view of the device shown in Figure 2.

Fi ure 5 is an enlarged section through the end of the leg and showing the adjustment for the ru ber foot.

In the drawings, l ke characters of references i d a e corre ponding parts in the several figures.

The lower part of an unbalanced window is shown in Fi ure 1 and comprises a s ll I,trim2 and the lower sash 3 which travels between stop beads 4 and arting strips 5 on either side of the window. The invention, now to be described, is made ri ht and le t for attachment to either side of the bottom rail 6 of the sash.

The invention, as shown in Figures 2 to 5, has the body portion 3 pressed from sheet metal into the fanciful shape shown in Figure 2. The upper portion 8 is bent over in a curve to form a gripping fingerpiece to lift the sash while the leg portion 9, at the side, is provided with a tongue H! which is rolled around to from the end of the leg into a tubing. A circular piece of rubber H is molded, in a T-shape in cross section as best shown in Figure 5, and the base of the T is received within the tubing I0 of the leg 9 so that 3 Claims. (Cl. 292-202") for frictional contact with exterior objects. In

order to adjust this foot in relation to the leg "9,

suitable annular rings l2 are first slipped over the base of the rubber foot before insertio'n'int'o the tubing lo and "as the foot wears, it can -be withdrawn from the tubing to and further annular rings added.

The main part of the body portion l is centrally provided with a hole'torec'ei've a rivet Li. A flat disc 1 4, having a central hole, isplaced behind the body portion and is received over the rivet which is then riveted lightly so that the disc H can freely turn thereon but without "coming off. Three equi-spaced countersunk holes 15 are provided on the disc, around the rivet l3, and the *countersinking is on the side adjacent the body portion 7. Just above the rivet t3 and slightly to the side, a hole It is provided in the body portion I which registers with the holes 15 in the disc when it is rotated.

"When the lifter and holder is to be "attached to thes'ash, the position thereon is'carefully noted so that the rubber foot H will contact the stop bead when the leg is at a downwardly sloping angle. The leg is then swung around until the rubber foot contacts the stop bead at an upwardly sloping angle. The disc M is rotated until one of the holes l5 registers with the hole IS in the member I. A fiathead screw is then inserted through both holes and screwed into the bottom rail 6 of the sash. The leg 9 is then turned, the flathead screw being in the countersink of the holes I5 and permitting such movement, until the next hole l5 registers with the hole I6 and a second screw is screwed into the bottom rail. This operation is repeated for the third hole and the device is then in place on the sash for operation. The right hand lifter and holder is attached in the same manner as above described and as the flathead screws are all in the countersink heads of the holes l5, they will be completely within the plane of the disc i and will not interfere with the rotation of the device thereon. It will be also noted that the fingerpieces 8 are positioned slightly more than a right angle from the leg portion 9.

In. operation the operator places the index fingers of each of his hands under the right and left fingerpieces 8. When lifting pressure is exerted by the fingers, the fingerpieces 8 pivot on the rivets It so that the said fingerpieces turn to a horizontal position which holds the legs 9 downward at an..- angle, with the rubber feet clear of' the stop be aids d. When the sash has been lifted the upper part of the T forms a projecting foot the required amount, the operator presses inward with his fingers on the fingerpieces so that the finger-pieces 8 rotate inward toward the center of the sash, thus lifting the rubber feet I I into contact with the stop beads 4. The supporting pressure of the operator's fingers is then released and the weight of the sash increases the outward pressure on the rubber feet against the stop beads and accordingly the sash is held at the desired position. To release the sash the operator again lifts same by the fingerpieces 8 and this time presses outwardly, which causes the legs 9 to rotate While the outward pressure is still maintained, the lifting pressure is reduced and the sash slides downward to the new position required or to the shut position.

If the lifter and holder is properly attached as described, it will be found that in the operating position of the device, the holes I B will be between the upper pairs of screws and accordingly the screws will not show through the said openings, and as the whole device is nicely chromium plated, a smooth finished surface is always presented to the eye, enhancing the general appearance of the window as a whole.

While I have mentioned that the holders and lifters are made right and left to be attached in pairs to the sash, it will be understood that one could be used with a fixed lifter on the other side. I have used two because the sash appears to operate much smoother and the support for the load is divided equally, relieving the sash from strain.

What I claim as my invention is:

1. A window lifter and holder, comprising: a bell crank rotatably mounted on the center of a disc; one of the arms of said bell crank having the end curved in a direction away from said disk to form a finger grip; the other of said arms of said bell crank carrying a rubber foot for frictional contact with exterior objects; said disc having a plurality of countersunk holes equidownward, thus clearing the rubber feet from the' stop beads.

spaced from the center of said disc; and a hole in said bell crank registerable with the holes in said disc, in the rotation of said bell crank on said disc.

2. A window lifter and holder, comprising: a bell crank having a long and a short arm and r0- tatably mounted on a disc; the short arm of said bell crank having the end curved to form a finger grip; the end of the long arm of said bell crank formed in a tubing to telescopically receive a rubber foot member therein; said disc provided with a series of holes equi-spaced from the pivot point thereof; and a hole in said bell crank, registerable with the series of holes in said disc, in the rotation of said bell crank on said disc.

3. A window lifter and holder, comprising: an L-shaped piece of flat metal, having the end of the long leg of the L rolled into a tubing and the end of the short leg of said L curved to form a finger grip; a disc positioned behind said flat metal and rotatably mounted thereon at the junction of the said legs; countersunk screw holes in said disc, registerable with a hole in said fiat metal, in the rotation of said fiat metal on said disc; a circular rubber foot member of T crosssection, telescopically receivable in the end of said tubing on the end of said long leg; and spacing washers receivable over the base of the T of said foot member and interposed between the head thereof and the end of said tubing.
